To all whom t may concern:

citizen of the United States ,residing at Janesville, in the county ofRock and State of have inventedcertain new and useful Improvements in Devices for Filling Fountain-Pens, of which the following is a to iill same, and t v out removing same specification. y

This invention relates to improvements in fountain-pens, and more particularly to a iilling attachment for that type of pens wherein the reservoir-comprises a'compressible tube fitting Within the barrel.

Asordinarily constructed it is necessary to remove the feed ortion of the pen in order is operation not only consumes a large amount of time, but is also `almost invariably the means of soiling the iingers of the operator.

The object of this invention is to produce a device of the character mentioned which will enable the reservoir to be quickly filled withfrom the barrel and which will not add materially to the cost of manu- Lto in the following facturing the pens.

For afull description of the invention and the merits 'thereof and also to acquire a knowledge of the details of construction'of vthe means for eHecting the result reference is to be-had to the following description and accompanying drawings, in which-d Y Figure 1 is a perspective view of a fountain en embodying my invention.' F1g. 2 1s a ongitudinal sectional view showing the pen in the act of being filled. Fig. 3 is a similar after being filled. Fig. 4 is a detail perspective view of the attachment comprising theinvention. l

Corresponding and like parts are referred description and indicated in all the views of the drawings bythe same referencey characters. The numeral 1 designates the barrel of a fountain-pen ofthe usual construction, and 2 the point or feed-section thereof. The reservoir of this pen is of the customary construction and' comprises a compressible tube 3,

, which is usually formed of rubber and is permanently attached to the feed-section 2. In

order to fdl the pen as thus constructed, it is commonly necessary'to remove the feed-section 2 and the reservoir and to compress the rubber tube while the pen-point is placed 1n the pressure upon the ink will then be drawn or sucked therein and the reservoir thus filled. lIn order to do away with this operation, a longitudinal strip 4 is placed within the lbarrel 1 and adjacent to the reservoir, with the end of the strip Said strip 5, which side of or thumb-screw 6, having an enlarged milled iinger portion raised above its lower end. When this thumb-screw 6 is screwed up tightly on the threaded lug 5, with its lower end in engagement with the outer side of the barrel 1 and with its enlarged milled portion passes through an opening 1n the uraised above suchouter surface of the barrel for convenient manipulation, the strip 4 is held against the side of the barrel 1, so that it does not in any manner interfere with the usual operation of the pen. When it is desired to fill the reservoir 3, the thumb-screw 6 is unscrewed so as to allow the lug 5 to be pressed inward. This causes the strip 4 to compress the reservoir-tube, so that by placingV the pen-point in an ink-w ell and releasing the lug 5 the ink will be drawn up into the reservoir. The thumbflush with the rear end of the reservoir.y

4 isl provided with a threaded lug v the ink-well.y Upon releasing the rubber tube i the barrel and is provided with anut j y screw 6 is then tightened so as to prevent any accidental compression of the reservoir, which would tend to interfere with the normal flow of the ink.

` Having thus described the invention, what is claimed as new is` lIn a fountain-pen, handle inclosing a laterally-compressible inkreservoir and provided with a pen-point and a lateral open1ng,a compressible strip located within the handle and havin a threaded stem projected through the sai lateral opening thereof, and a pressure-knob mounted upon the projecting end of the stem vto serve las a clamp-nut, or an adjustable stop and finger-piece according to thefposition of the knob with reference to thehandle, threaded stem and compression-strip.

In testimony whereof I aiiix my signature in"presence of two witnesses.
